I have a theory about Peter. I think he's going to explode, just as his visions and Isaac's paintings show. I have a theory about Hiro. I think he's going to travel through time, trying to fix everything, after Peter destroys the city.

Let's look at what happens to people with powers:

Shanti dies as a child, of unknown causes, but likely related to her power.

Claire's life is turned upside down.

Simone is shot.

Isaac loses Simone, twice.

Hiro brings the family shame (a big deal in Japanese culture).

Matt loses his job, then steals diamonds.

Nathan is shady, but it's not clear (yet) how his powers influenced him.

Peter is becoming increasingly dangerous, and is going to blow up.

The Haitian causes brain damage.

Hana loses her job and now distrusts everyone.

Micah steals from an ATM.

Niki turns into evil Jessica.

DL is on the run from the law.

Meredith loses her daughter and went into hiding (not sure why).

Claude is shot and went into hiding.

Ted loses his wife and then blows himself up.

Eden's life is pretty messed up before Bennet, and she's recovering, but she ends up shooting herself.

Gabriel (Sylar) goes on a killing spree after finding he has powers.

Charlie is killed by Sylar (for eidetic memory).

Brian Davis is killed by Sylar (for telekinesis).

Zane Taylor is killed by Sylar (for liquefaction).

Dale Smither is killed by Sylar (for super hearing).

What's the theme here? Having powers leads you and people around you to get hurt. For many of them, power corrupts. Take a look at Micah, DL, Niki, Hana, Meredith, Claude, Ted, Eden, Gabriel, and maybe Claire, and you'll see good people who are led astray by their powers. The other characters aren't necessarily corrupt but just having those powers has led to trouble.

Basically, these powers hurt everyone.

The most dramatic will be when all the heroes end up in New York City, and Peter blows them and the city up in the season finale. Everyone will die.

The only solution to all of this is to stop people from having their powers, or at least teach them how to use powers responsibly. It's already too late to do this in the current timeline. The solution lies in the past. Hiro is the only one who can go back in time to fix everything. So he will, at the end of this season. That's my theory.

In Heroes episodes 15 and 16 (Run and Unexpected), Claire starts to believe her father and the Haitian are behind her mother's memory loss. I think Claire's going to leave Texas and head to New York.

What's keeping her in Texas?

Her father. However, she's starting to hate her father for what he's done to her mother. She wants to get away from him. (I wonder what he'll do to the Haitian now that he knows Claire's memory wasn't wiped.)

Her mother. Claire is really worried about her mother.

Her brother Lyle. His memory was wiped, and he's not making much of an appearance in the show anymore.

Her friend Zach. His memory was wiped as well, and he's also not making much of an appearance in the show.

Her biological mother, Meredith. She's gotten some money from Nathan, and she's heading to Mexico, so she won't be in Texas for much longer.

Only her mother is keeping Claire in Texas. I think her mother will die very soon, and Claire will no longer have any need to stay in Texas. She'll head to New York to find Peter, and eventually meet her father Nathan.

Let's start with Simone's father, Charles Duveaux. Before he died he mentioned that he saw himself and Peter flying around the city. He didn't know that Peter could fly. Why would he have dreamed this? I think Charles has the power of visions. Peter, being around Charles, absorbed that power. That's why Peter is able to see visions (for example, of Nathan flying out of the car before it crashed). This is similar to but separate from Isaac's power of painting the future (which may be prediction or may be causing it—not sure!).

We also know that having a power is genetic (from Chandra's research), and that it's inherited (Micah, Claire, and that little girl that Matt saved). The specific power is not inherited, just that they have one.

Putting the two together, Simone very likely has a power.

What power would she have? She liked Isaac when he had a drug problem, and liked Peter when he was in trouble. She likes people in trouble. She wants to help them. I think her power involves helping others, perhaps healing them, perhaps projecting powers onto them. If it's the power of projection, her power probably is not of much use, since she has no other power to project. But when Peter absorbs that power, he might be able to project Claire's power of healing onto Simone. And that would bring Simone back from the dead.

Why am I convinced Simone should come back? Ignoring the Neo/Trinity to Peter/Simone parallel (did you see how Peter stopped bullets?), the main issue is that Simone was in Peter's future vision when Peter blows up. I think Isaac was pulling Simone away from Peter in that vision. So I think she needs to be alive. On the other hand, the visions are not predictions, and don't have to be taken literally. Charles's vision for example never came true; it was merely expressing the idea of flight, and the details weren't accurate.

While it's possible that Simone will stay dead, I'm betting Peter won't show up for several epsiodes, then he'll bring her back to life, and then she'll leave the storyline for other reasons.
